<p>A self-shielding, flux cored arc welding electrode for joining Ni-Cr-Fe alloys and overlaying dissimilar metals. The wire has a nickel-chromium containing alloy sheath and a flux core containing special proportions of carbonates, fluorides, metal oxides, and powdered metals. Sound welds can be prepared without the use of a supplement inert shielding gas. Welded joints provide essentially the same properties as those of the Ni-Cr-Fe base alloy.</p> |
